JOHN HEBERLING, OF ROOHESTER, NEW `YORK.`

.i DUMPING-wAeoN.

To a/ZZ whom it may concern:

` B e it known that I, JOHN HEBERLING, of

the city of Rochester, in the county ofMonroe. and State of New York,have invented l certain new and useful Improvements. in Dumping-Wagons;and I do hereby declare the following tobe a full, clear, and exactdescription of'the same, reference being had to the accompanyingdrawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention relates to dumping'f wagons, and particularly tothat class 1n whlch the contents of the box are deposited by an openinmovement of the bottom sec-` tions; and it as for, its object to providean limproved means for movably attaching said sections t'o the wa on-boxand also mechanism for operating t em whereby they may be tightly closedand when released will be allowed to swing clear of the depositedVmaterial. I To these and other ends my invention consists in certainimprovements and combinations of parts, all 4as will be hereinafter morefully described, the novel features being pointed out in the' claims atthe end of this specification. y In the drawings, Figure 1 isa top plan.view 'of awagonbox,illu`strating the mechan-V ism embodyingmy inventionapplied thereto.` Fig. 2- is a front elevation, partly in section, takenon the line 2X 2X of Fig. 1; 3 isa longitudinal-sectional'view on thehne 3X view onthe lineflfl 4X of Fig. 1.' Fig. 5 is a. detail sectionalview on the line 5 5X of Fig.

3X of Fig.. 2.I Fig. 4 is a transverse sectional i Patented Jan. 8,1907.

'movable sections 6 and 7, extending longitudinally of the wagon-box,their approximate edges meeting at the center thereof, as shown. Eachofthese sections is supp'orted at its forward andl rear ends upon hingemembers comprising vertically-extending faces 10, extending over theends of the sec- .tion,.having' flanges 15, forming supports forthesections, and also provided with ears 16, by means of which they'aresecured .to the end-boards 3 and 4 their intles or pivotal points 17being supported 1n the offset zends 'e 18 'of `straps 19. By arrangingthe hinge members aththe ends of the box their pivotal points may belocated abovethe plane of the `bottom ofthe wagon and between theproximate faces of the side-boards 1 and 2, so that when the bottomsectiolisare released their inneredges will swing downwardly andOutwardly and their outer edges will swing out- VWardly andl upwardly,so that vtheir lower edges when opened will be supported a considerabledistance from' the ground to avoid the pile of deposited material, saidouter edges A being adjacent to the sides of the boxa feature whichenables me to provide a wagon-box of the standard depth or of evengreater depth, if desired, without increasing vthe height of. the boxfrom the ground.

To facilitate the outward movementof the sections "and 'to forni a tightjoint between the bottomand the sides ofthe box, I round the bottomedges ofthe latter on arcs having thepivotal. points 17 as centers, andalso rounder/curve ,thel outer bottom corners of the ends 3 anda, asindicated at2-0 in Fig. 4, the outer edges of the bottom sections 6 and'7-being correspondingly curved, asindicat'ed at 21, to fit the curvedportions of the box.v

. sustaining the Weight of the load'or in case of engagement with thedeposited material when the wagon is being drawn away. A

Arranged intermediately of the'end-boards additional hingeI members areprovided 'by upwardly-,extending arms 210, journaled 'on pivots 22'",supported in channel-plates 23. The latter are open at their rear andbottom sides and. are provided. with laterally-extending faces orflanges 24,. through which pass screws or bolts 25, securing them totheir re- -5 5 l The bottom of the wagon is composed of spectiveside-boards 1 and 2 in alineinent n boards, and I also withslots 26,formed therein to' permitTthe outward moven'ient of the arms 210. The

ytached to the bottom sections, as will be fur-y ther described, andalso connected to the drums at points near their bases or larger ends,whereby the initial movement imparted to the shaft 31 will cause thebottom sections to be drawn quickly into their normal horizontalposition. Asl these sections approach their position the chains orcables travel toward the smaller ends of the drums or cones,

thus reducing the levera e required to operate the shaft 31 and enab ingthe operator Vto exert a greater ower to draw and secure the doors intothe clloscd position. v

` Owing to the difficulty occasioned by the une ual stretching ofchains, cables, or other ilexi )le connections employed for closing theopposite ends of the bottom sections oi' a wagon which allows one end orthe other to sag after a comparatively vshort use, I provide means forequalizing them, consisting in the present instance of an intermediatesection of cable or chain 40, attached to each of the end portions 35and 36 and extending beneath the bottom section 6 and held'loosely inplace by means of eyes or thimbles 41. In order to close both of thebottom sectionsfby means of a single flexible connection, I pass thecable or chain over a support in the form of a roller or pulley 42,journaled in the strap 43, arranged centrallyupon each of the endrovidea similar support or pulley 44 on each) end of the section 7 and beneathwhich the cables or chains extend, as shown particularly in Fig. 2.chains or cables 35 and 36 are attachedto the bottom section, which isfarther removed from the winding-shaft, and are permitted to slip ortravel around the supports or ulleys 44 on the nearer or adjacentsection t ereto, it will be seen that the latter section will be `closedin' advance of the former, and thus cause the covering-strip 28 to beroperly positioned over the meeting edges o the two sections each tlmethey are closed.

The. handle 45 for rotating' the windingshaft is journaled thereon atits forward end and carries a awl 46, adapted to coperate with theteetlril in a ratchet-wheel 47 when rotated inthe direction indicated bythe arrowin Fig. 6 and having the end 48 adapted As the wheel is-adetent 50, pivoted on an arbor 5].

and normally held in operative position by a spring 52. y As thesections are pivoted, as lbefore described, on cent-ers arranged abovethem and located between the sides oi the wagon-box, they will, ifo enedinto a moreor less vertical position by the downward movement of thecontents of they box, draw thechains or cables outwardly; but when theyare freed they will rotate into the position indicated by the dottedlines in Fig. 4.

The cables or chains having been drawn outwardly sufficiently to allowthe bottom sections to open outwardly to their limit of movement, theywill ordinarily sag downwardly and hang loose, as the sections swinginwardly toward each other when they are free of the deposited material.To take up the slack in the cables or chains 35 and 36 thus occasioned,I provide a tension device, such as a spring 53, secured at one end tothe Wagon-box (shown at 54) and attached at its o posite end to a collar55, journaled on the s aft, and provided with ratchet-teeth 56, adaptedto enga e corres ending' teeth on a sleeve 60, secure to the siiaft 31by 'a' pin 61, but permitting a longitudinal' movement thereon todisengage the tension device when desired. The latter', it will'beunderstood, may be adjusted'by the rotation of the collar 55, so thatthe bottom sections may be entirely closed, the operator being then onlyrequired to partially rotate the' winding-shaft to firmly secure andlock the bottom sections tightly against the box.

It is desirable, however, that the tension device be 'prevented fromoperation until the wagon has been drawn away from the depositedmaterial, and to this end the shaft is further provided with aratchet-wheel 62, the teethof which extend in a direction opposite' tothose-upon the yratchet-wheel 47. A dog o'r pawl 63,locat'ed adjacentthe detent on the arbor y51, is held in the operative position by meansof a spring 64, similar to the spring '52. As the pawl 50 operates torevent a rotation of the shaft 31 and to hol the bottom sections in aclosed position and the dog or pawl 63 operates to prevent the rot-ationofthe shaft lunder the action of the tension device 53, I

provide a means for alternately moving them into and out of operativekposition. In the present instance this is accomplished by' a leverpivoted to the side-board 2 and having a i forwardly-extending end 630,provided with a lateral extension 640, which may be engaged anddepressed by the operators foot. Pivoted t'o this extension is afoot-operated latch 65, having a nose or point adapted to engage aertures 66 or 67, formed in a plate 68 to ho d the lever againstaccidentall ICO IOS

operation', either to release the wagonbot ,tom or the tension device.:The rear end 69 of this lever extends beneath the detent `50 and thelpawl 63Iand is provided with two shoulders 70 and 71, respectivelycoperating therewith, so that when theend 69 of the lever is elevatedthe detentj50rwill be moved outwardly to the inoperative position, and.`the pawl 63 will be released and moved inwheel 62 by its wardly intoengagement with the ratcheting 64.

r At the forward end of the wagon-box l.

providestay-ehains 75and 76, both of whichV are connected atone end toan eye 77 on the front board 3 and attached at their outer ends to thecorners of the sections 6 and- 7, respectively, for the pur-pose ofpreventing the sections from being' subjectedto any undue strain as maybe occasioned by an attempt on the part of the operator to turn thewagon at an angle while it is above thematerial just deposited.

A dumping-wagon embodying my invention is simplein construction andconsists of few parts, which may be readily formed and assembled. Thearrangement of the hinge members whereby their pivotal points" arelocated above the plane of the bottom and within the sides of the boxaords a sup ort .for the bottom sections, preventing t em` from saggingand allowing 'them to swingl outwardly and upwardly when released awayfrom the deposited material-without danger of their edges engagingtherewith. l i
